What is AMS, ISF ? and what does it mean ?

AMS = Advanced Manifest System (Shipping carriers must report their cargo to destination customs before sailing).

ISF = Importer Security Filing (Prior to loading into container or onto ship, a counter party at destination must register your cargo into the customs system - a kind of AMS reconciliation hand shake).

Non compliance can result in fines up to or exceeding US$5,000.

To comply with the advanced filing requirements a registered customs agent or freight forwarder at destination must be appointed - they also assist with shipping company & customs liaison and can assist with import customs clearance (and transportation where required).
